<p>PURPOSE:To reduce the influence of the reaction of a door gradually and enable a motor to be miniaturized by driving the motor to move a swing member and a swing projection rotationally, and by applying pressure to the side wall section of a working member, to shift the member from a door releasing position to a full closing position one after another. CONSTITUTION:When a motor 43 is driven, the a rotary shaft 46 is rotated, and a swing member 56 and a swing projection 61 are swung around an axial core by a specified angle. After that, by the swing projection 61, pressure is applied to the side wall section of a working member 57, and the working member 57 is shifted to a door releasing state, a half closing state, and a full closing state one after another. Then, in the door full-closing state, the wall surface of the side wall section of the working member 57 is set orthogonally to a virtual line for connecting a space between the axial core of the rotary shaft 46 and the axial core of the swing projection 61. As a result, according to the closing working of a door, the influence of the reaction of the door is reduced, and load torque working on the rotary shaft 46 and the motor 43 is reduced, and the motor 43 can be miniaturized.</p> |
